me with this you.

what is the original number? you forgot to add it.

the answer is (-4,-4)

hope this ! : d

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.

step-by-step explanation:

the answer for the second equation is (4,0)
